Fifteen years ago Johnny Mack Cahill left his hometown of Noble's Crossing, Alabama without a penny to his name, vowing to never return. Johnny settled in the Houston area and became a successful wealthy businessman. Now Johnny has received an anonymous note and newspaper clipping from his hometown, stating: "Your son needs you. Come home." The trouble is, Johnny Mack never knew he had a son.

The accompanying newspaper article states that Lane Noble Graham is the prime suspect in the murder of her ex-husband Kent Graham. It shows a picture of Lane's 14-year-old son Will, who is the spitting image of Johnny Mack. The only problem is that he never slept with Lane, so who is Will's biological mother?

Johnny returns to Noble Crossing to meet his son and to learn the truth about Will's biological mother, who sent the note, and who killed Lane's husband. As he begins his search for answers, a killer will murder again to keep certain secrets hidden.
